ACETYLENECARBOXYLIC ACID ETHYL ESTER;ETHYL ACETYLENECARBOXYLATE;EPL;(Ethoxycarbonyl)acetylene;2-Propynoic acid; ethyl ester;Ethyl 2-propynoate;Ethyl propynoate
It is used as a precursor in the preparation of substituted anthraquinones and pyrazolo[1;5-a]pyridine; which exhibits anti-inflammatory activity. Further; it is employed in the synthesis of benzene-1;2;3;5-tetracarboxylates promoted by triphenylphosphine. Its halogenated derivatives are used as a substrate for direct; asymmetric alkynylation of cyclic beta-ketoesters using chiral phase-transfer catalysts.
